Here are two steps from the derivation of the quadratic formula (image w question below)

Answer: 10y

Step-by-step explanation:

4(y-2)+6y+8

4(y-2)=4y-8

4y-8+6y-8

*8's cancel out*

6y+4y=10y

Answer:

---------------------------------

Given sequence:

This is decreasing sequence since the common difference is negative, d = - 8.

Therefore the first term is the largest one:

The equation and solution of the problem are 3/8-7/8 and 1/2.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

Given;

The food parrot eats = 3/8pounds

The food cat eats = 7/8pounds

Now, food eaten more by cat =7/8-3/8

=(7-3)/8

=4/8

=1/2

Therefore, the answer to equation will be 1/2.

The solution to the indices is 50.

Index (indices) is the power or exponent which is raised to a number or a variable. The plural of index is indices. Indices contain constants and variables. The constant is a value which cannot be changed and a variable quantity can be assigned any number or its value can be changed.

Indices are a convenient tool in mathematics to correctly denote the process of taking a power or a root of a number. Taking a power is simply a case of repeated multiplication of a number with itself while taking a root is just equivalent to taking a fractional power of that same number.

8^1/3 / 5^-2

Applying the necessary laws of indices;

A continuous random variable is one that has a range of possible values. In other words, if a random variable adopts a value that fits within a specific range, it is said to be continuous.

Measurements like height, weight, and time are all represented by continuous random variables. A continuous random variable is represented as the area under a density curve. The concept of a continuous random variable, as well as its mean, variance, types, and related examples

P(X < 0.35) = 0.35

P(X = 0.35) = 0 since X is a continuous random variable and the probability of a specific value is 0.

P(0.35 < X < 1.25) = 1.25 - 0.35 = 0.9

P(0.10 < X < 0.20 or 0.6 < X < 0.9) = (0.20 - 0.10) + (0.9 - 0.6) = 0.3

P(X < 0.5 or X > 0.6) = (0.5 - 0) + (1 - 0.6) = 0.9

The indicated measures:

m∠ABC =  138° and m∠BCD = 52°.

According to the Angle Addition Postulate, an angle's measure is equal to the sum of the measures of any two adjacent angles. The Angle Addition Postulate can be used to determine the measurement of a missing angle or to determine the angle produced by two or more other angles.

Given:

The angle measures:

m∠DAE = 16° and m∠EDC = 64°.

The diagonals of the kite intersect at 90°.

(1).

In ΔAED,

the sum of all the angles of the triangle is 180°.

m∠DAE + m∠ADE + m∠AED = 180°

m∠ADE = 180 - 90 - 16

m∠ADE = 74°

According to the angle addition postulate,

m∠ADE + m∠EDC = m∠ADE

m∠ADE = (74 + 64)°

m∠ADE = 138°

From the property of kites,

m∠ADE = 138° =  m∠ABC.

(2).  m∠EBC =  m∠EDC,

m∠EBC = 64°

In ΔBCD,

the sum of all the angles of the triangle is 180°.

m∠DBC + m∠BCD + m∠CDB = 180°

m∠BCD = 180 - 64 - 64

m∠BCD = 52°

A journal entry is a format used in accounting to record transactions. The amount we owe someone else that we must get in the future is known as notes receivable.

Notes receivable are claims for which official documents of credit, like promissory notes, are issued as proof of debt. In most cases, the credit instrument has a minimum term of 30 days and imposes an interest payment obligation on the debtor.

Given the following information:

Note receivable $15,000

Rate of interest 9%

Discount rate    12%

Period              2 months

Preparing journal entry to record accrued interest

To prepare the journal entry, we must first calculate the interest. We can compute interest by multiplying the notes receivable, the interest rate, and the period, i.e.

Interest = Notes receivable × Rate of interest × Period

Interest = 15000 × 0.09 × 2/12

Interest = 225

Now we can prepare the journal entry

Date                          Particulars              Debit ($)               Credit($)

February 28, 2016     Interest receivable        250

                                          Interest                                    250

                           To record accrued interest  

Preparing the journal entry to record discounting

To begin preparing the Journal entry, we must first calculate the necessary data.

We can calculate the cash as the difference between Maturity Value and Discount. That is,

Cash = Maturity Value – Discount

The value of Maturity is unknown. We can compute it as the sum of the receivable notes and interest. That is,

Maturity Value = Notes receivable + Interest

Interest =Notes receivable × Rate of interest × Period

= $15,000 × 0.1 × 6/12

= $1,500 × 0.5

= $750

​Maturity Value = Notes receivable + Interest

= $15,000 + $750

=  $15,750

Discount =Maturity Value × Discount rate × Period

= $15,750 × 0.12 ×  4/12

= $1,890 × 0.33

= $630

Finally, we can calculate cash

Cash = Maturity Value – Discount

= $15,750 − $630

= $15,120

Loss on sale = Cash – Notes receivable - Interest

= $15,120 − $15,000 − $250

= $130

Finally, we can prepare our journal entry.

Date                        Particulars                   Debit ($)            Credit($)

February 28,2016     Cash                            15,120

                              Loss on sale                      130

                              Notes receivable                                               15,000

                                  Interest                                                  250

                       (To record discounting)

Therefore , the solution to the given problem of slope intercept comes out to be  dy/dx = -1/2.

After you are certain if Y = mx + b, the gradient intercept approach can be employed. By using just one particular point on the line and its slope, the direction form is a way to represent an axiom for a line. The slope is defined as such rise across run and is represented first by point form (x,y), and may be calculated using the slope intercept method, y = mx + b. (0, b). By using just one specific statement on the vector and its slope, the direction form is a technique to write a linear model for a line.

Here,

Given : x² +2xy - 2y² +x =2

thus,

To find the gradient at point (-4,1) :

We have to find the dy/dx

so,

=>  2x + 2y + 2xdy/dx -2ydy/dx +1 =0

=> dy/dx (2x-2y) = -(2x+ 2y) -1

=>dy/dx = -(2x+2y) -1 / (2x-2y)

So , at the point (-4,1)

=> dy/dx = -(-8 + 2) -1 / (-8 -2)

=>dy/dx = 5/-10

=>dy/dx = -1/2

Therefore , the solution to the given problem of slope intercept comes out to be  dy/dx = -1/2.

Step-by-step explanation:

it us a polynomial with a second degree variable

When the number of times you roll an odd number increases, the theoretical probability that you roll an even number would decrease.

As the number of times you roll an odd number increases, the theoretical probability that you roll an even number decreases. This is because the probability of rolling an even number is inversely proportional to the number of times you roll an odd number.

If you are rolling a fair die, the probability of rolling an even number is 3/6 or 1/2, and the probability of rolling an odd number is also 3/6 or 1/2.

As the number of times you roll an odd number increases, the number of rolls that are left for an even number decreases, thus the probability of rolling an even number decreases as well.

For example, if you roll the die 10 times and 6 of them are odd numbers, the probability of rolling an even number in the remaining 4 rolls is 4/4 or 1 (100%) because you are guaranteed to roll an even number.

The power series ∑aₙxⁿ is an infinite series and looks like a function of x. An easy way to illustrate the idea of a power series representing a function is to use the geometric series as an example.

The power series is a very important kind of infinite series where the terms contain the powers of a variable. A power series is a series of the general form:

∑aₙ(x-x₀)ⁿ=a₀+a₁(x-x₀)+a₂(x-x₀)²+a₃(x-x₀)³+.........

called a power series centered at x₀

where  x is a variable,

x₀ is a real constant, and the

aₙ's are real constants called the coefficients of the series.

The given power series representation is f(x) = arccot(x).

we observe that f '(x)=-1/(1+x²) and find the required series by integrating the power series for -1(1+x²)

arccot(x)=∫-1/(1+x²)dx

⇒∫-(1-x²+x⁴-x⁶+....)dx

⇒C-x+1/3x³-x⁵/5+1/7x⁷-......

To find C we put x=0 and obtain C=arccot(0)=π/2
